The immune systems of human and non-human primates have diverged over time, such that some species differ considerably in their susceptibility, symptoms, and survival of particular infectious diseases. Variation in primate immunity is such that major human pathogens - such as immunodeficiency viruses, herpesviruses and malaria-inducing species of"Plasmodium"- elicit striking differences in immune response between closely related species and within primate populations. These differences in immunity are the outcome of complex evolutionary processes that include interactions between the host, its pathogens and symbiont/commensal organisms. The success of some pathogens in establishing persistent infections inhumans and other primateshas been determined not just by the molecular evolution of the pathogen and its interactions with the host, but also by the evolution of primate behavior and ecology, microflora, immune factors and the evolution of other biological systems.

To explore how interactions between primates and their pathogenshave shaped their mutual molecular evolution, "Primates, Pathogens and Evolution"brings together research that explorescomparativeprimate immune function, the emergence of major and neglected primatediseases, primate-microorganism molecular interactions, and related topics. Thisbookwill be of interest to anyone curious as to why infectious diseases manifest differently in humans and their closest relatives. It will be of particular interest to scholars specializing in humanand non-human primate evolution, epidemiology and immunology, and disease ecology."Primates, Pathogens and Evolution"offers anoverview and discussion of current findings on differences in the molecular mechanics of primate immune response, as well as on pathogen-mediated primate evolution and human and non-human primate health."

Erythrocytes of the Rhesus and Cynomolgus Monkeys addresses the morphologic, quantitative, and generative aspects of the erythrocytes of the rhesus monkey Macaca mulatta and the cynomolgus monkey Macaca fascicularis (long-tailed macaque, crab-eating monkey). These two species are the most commonly selected nonhuman primates for basic science and clinical medical investigations. The hemopoietic cells of man and the rhesus monkey display an intimate homogeneity. Their functional activities are close and at times identical. The cynomolgus monkey was enlisted in biomedical studies at a time when rhesus monkeys were not available in sufficient quantities. It has gained increased use in the Far East and in the Western world. It is, for example, employed in the current development of a vaccine against the deadly Ebola virus. The authors of the book discuss the erythropoietic profiles of normal and abnormal macaques of both sexes and of all age groups as investigated with contemporary electronic methodologies. They cover the role of stress as it is perceived by the monkey and how it impacts erythrocellular values, and how to train the monkey to be a cooperative, unperturbed subject for hematologic study. Additional topics include the role of medication in deriving normal physiologic erythrocellular data, the development of the precursors of the erythrocyte (normoblasts), the morphologic analysis of the megaloblastic series of abnormal erythroid cells, the analysis of erythropoiesis in bone marrow, the relationship of the simian immunodeficiency virus and erythropoiesis, erythrocyte life span, and parasitic invasion of the red cell.
